Radiation transport refers to the process by which radiation, such as light, heat, or nuclear radiation, moves through different materials or environments. This movement can be influenced by various factors, including the type of radiation, the properties of the medium it travels through, and the presence of obstacles. Understanding radiation transport is essential in fields like medical imaging, nuclear energy, and environmental science. In radiation transport, interactions can occur, such as absorption, scattering, or transmission. These interactions determine how much radiation passes through a material and how much is absorbed or redirected. Accurate models of radiation transport help scientists and engineers design better systems for radiation protection, energy production, and medical treatments.
